Germany had the better tank (Tiger and King Tiger)but could not produce them on the same scale as the Russians produced the T-34 . Quality vs Quantity .

Yes Germany did use tanks during world war 1, they use tanks alone with airplanes, gas masks, and submarines
it was when Germany broke the peace treaty and attack russia on 1942 with 300000 men and 3000 tanks
Tanks were in development after WW1, mostly by Germany.
Russia has 21,790 tanks and world s' largest tank army.
yes,but for trade
Not quite sure what you mean by 'special'. WWII tanks were certainly better than WWI tanks.
Germany's first tanks were captured British tanks; they simply painted German emblems on them and sent them back against their former owners.

Nearly all nations use tanks. They purchase them from: US, Russia, China, Britain, Germany, France, to name a few. Japan produces tanks for their own military, but generally do not sell them to other nations (due to laws placed upon them after WWII).
Britain, Germany and France all used tanks in WW1. The British had them first and had the most.
Britain, France, and to a very limited degree, Germany.
